Army XVIII Airborne Corps Fort Bragg, North Carolina Private First Class Sean Brennan's heart raced as he approached the regimental headquarters building. For the hundredth time in an hour, he wondered why he'd been summoned here in such an unorthodox manner. He feared he knew the answer and secretly dreaded that today would be the day the truth came out. I must have been crazy to think I could get away with it, he thought glumly. He removed his cap and rubbed his hand over the military stubble on his head - a nervous habit he'd had since he was a kid back in Massachusetts. As Private Brennan approached the structure - which looked more like a big colonial house than the military command center for one of the busiest regiments of the U.S. Army - he felt a sense of awe mingled with rising fear and apprehension. He had never been this close to officer country before. Yet the building itself was deceptively innocuous-looking.
